Abstract

PURPOSE:To suppress excessive transient fluctuation by connecting a looping clamp circuit between an input and an output terminals of a current controller. CONSTITUTION:A looping clamp circuit 20 is composed to form the signal in such a manner that the output signal VGPG of a control compensation circuit 5 which consists of a voltage controller 5A and a current controller 5B is received by the looping clamp circuit 20 and, by comparing this output signal VGPG to the standard voltage VCL, the output signal VGPG of the current controller 5B is made identical with the standard voltage VCL when the signal VGPG exceeds the standard voltage VCL. At the same time a low level priority circuit 30 is composed in such a manner that the priority is given to one of the output signals of the voltage controller 5A or of the looping clamp circuit 20 which has the lower signal level. Accordingly, when the output signal VGPG of the current controller 5B exceeds the clamp level VCL the clamp controller 20A operates and the output signal of the current controller 5B is clamped at VCL. When the output signal of the current controller 5B is below the clamp level the clamp controller 20A does not operate and the current is directed by the voltage controller 5A.
